CNTF and autism: The CNTF levels did not differ significantly between sham, autism serum, autism serum+P6, and control serum groups (Fig. 6E and F; ANOVA, p = 0.068, Bonferroni’s post-hoc test, p>0.05); however, there was a significant increase in CNTF expression in control serum+P6 group compared to control serum alone group (Fig. 6E and F; Bonferroni’s post-hoc test, p>0.05; Student’s t-test, p = 0.0155).
